1 76GHz Millimeter Wave Automobile Radar using Single Chip MMIC Shinichi Yamano Hirofumi Higashida Masayoshi Shono Sadanori Matsui Tomohiko Tamaki Hidekazu Yagi Hisateru Asanuma Abstract In the latter half of the 1990s, auto manufacturers released driving assistant "Adaptive Cruise Control (ACC) Systems" that utilized Millimeter Wave radar. Then in 2003 this technology started being applied to safe driving support in the form of "Collision Mitigation Systems." In the future, Millimeter Wave radar is expected to undergo performance improvements that will enable it to be adapted to all driving situations, and continued reduced pricing is expected to lead to an expansion in a wide variety of models that adopt it. As an approach to price reduction aimed at expanding the use of Millimeter Wave radar, FUJITSU TEN LIMI- TED developed a single chip for Monolithic Microwave Integrated Circuit (MMIC) modules in Millimeter wave transceivers and also developed radar that utilizes that technology. This report describes a 76GHz Millimeter Wave radar using such single-chip-mmic. This low-cost radar will be produced on a commercial basis from this point forward. 12
